KIMIKO Date-Krumm is positively youthful in comparison to some veteran sports stars.

Date-Krumm stunned the tennis world by beating No.2 seed Maria Kirilenko this week, but we've found a few more old performers to make you consider getting off the couch this weekend.

Check out our list of oldies but goodies.

EQUESTRIAN - HIROSHI HOKETSU

What's your grandpa doing these days? Bet he's not saddling up a horse and competing at the Olympics. Yeah, dressage isn't quite as taxing as boxing or a marathon, but Japanese rider Hiroshi Hoketsu competing at the ripe old age of 71 is still more than impressive. Hoketsu competed at his first Games in 1964 and finished 40th in the dressage event in London as the third oldest Olympian in history.

NETBALL - IRENE VAN DYK

Statistically, Irene van Dyk should probably have done her knee at least four times by now. It's a testament to the 41-year-old Kiwi netball star's peerless work ethic that she's remained largely injury-free and continues to dominate in one of the most brutal sports for knees and ankles. Just this week she shot 27 goals from 29 attempts as the Silver Ferns lost the second match in a five-match series against Australia.

AFL - DUSTIN FLETCHER

People have been predicting Dustin Fletcher's retirement for the better part of a decade, but the ageless Essendon defender shows no signs of stopping yet. The 38-year-old helped the Bombers secure a premiership in his first season in 1993 and another in 2000 and could top the mystical 400-game mark if he plays every game next year.

CYCLING - CHRIS HORNER

Cyclists actually tend to get better with age, but surely there's a ceiling on that? Apparently not, as 41-year-old Chris Horner proved when he won the Tour of Spain this month - marking the biggest win of his career in his 19th year of professional road racing.

SURFING - KELLY SLATER

It's somewhat of an indictment on the rest of us that probably the coolest person in the universe is 41. But it's Kelly Slater, and he's still winning world surfing championships. The American won his last title two years ago and has already won two events this year to sit second in the world rankings. Freak.

TRIATHLON - CRAIG ALEXANDER

Most 40-year-olds are starting to plot their retirements. But then most 40-year-old aren't Craig Alexander, who likes to head out for a lazy 3.8km swim, 180km bike ride and 42km run just for kicks. The 2008, 2009 and 2011 Ironman World Championship winner finished 12th at last year's event and third at the Ironman Asia Pacific Championships earlier this year.

HORSE RACING - BART CUMMINGS

Doing the same job for sixty years seems tantamount to torture, let alone when waking up before dawn every day is part of the gig. It's unlikely anyone will ever equal 85-year-old trainer Bart Cummings' staggering list of achievements, particularly his 12 Melbourne Cup winners. He trained his first Cup winner, Light Fingers, in 1965 and his most recent, Viewed, in 2008.

UFC - RANDY COUTURE

Couture just didn't know when to quit what is arguably the most brutal sport in the world. But when you love being hit by dudes, you love being hit by dudes. Couture, now 50, fought his last UFC bout in 2011 when he was knocked out by Lyoto Machida in the second round. But he remains the only person over the age of 40 to have won a UFC championship bout - something he did four times.

FOOTBALL - MARK SCHWARZER

There are older footballers around, but let's recognise one of our own. Mark Schwarzer still has dibs on Australia's No.1 goalkeeper spot ahead of next year's World Cup, despite being 40 years old. The Chelsea keeper has been capped for his country 108 times and continues to front up after turning to the world's greatest diet, which includes steaks for breakfast, in a bid to prolong his career.

BASKETBALL - ROBERT PARISH

One of the few aging sportspeople to go out on top, Parish's final game at the age of 43 came as the Chicago Bulls wrapped up the 1996-97 NBA Championship. It was his fourth title after winning three at Boston in his 1611-game career.

ICE HOCKEY - CHRIS CHELIOS

When NHL veteran Chris Chelios suited up in the latter part of his career, he was playing alongside teammates who weren't even born when he first took to the ice for the Montreal Canadiens. Chelios was drafted in 1981, first played in 1981 and finally hung up the skates in 2010, having missed the playoffs just twice in his entire career.

GOLF - PETER SENIOR

The name said it all for old Pete when he saluted at last year's Australian Open. Aged 53, the Aussie golf stalwart belied his years and younger competitors to seal his 13th win on the Australasian Tour, 33 years after his first at the South Australian Open.
